Impacts of weather and climate on mortality and self-harm in Finland

Reija Ruuhela

Human beings are able to adapt to their climatic normal conditions, but weather extremes may pose a substantial health risks. The aims of this dissertation were to model the dependence of all-cause mortality on thermal conditions in Finland, and to assess changes in the relationship over the decades and regional differences in the relationships between hospital districts. Another aim was...

Telecouplings in a globalizing world: linking food consumption to outsourced resource use and displaced environmental impacts

Vilma Sandström

Globalization has increased the interconnections between world regions. The distal socio-economic and environmental interactions, feedbacks and outcomes between land systems are called telecouplings. The increase in telecouplings is also true with agricultural production and food systems as food trade has intensified in the past decades. This change has contributed to many positive aspec...

Thermodynamics and dynamics of polar ice sheets, glaciers and ice shelves under changing climate

Ilona Välisuo

Polar ice sheets, glaciers, and ice shelves, referred to as land ice in this document, are under transition in the changing climate. Observations show that glaciers have retreated and melt water discharge from land ice has increased together with the warming climate. Decreasing volume of land ice is reflected to the whole Earth system via changes in surface radiation balance, sea level r...

Deep Brain Stimulation of the Subthalamic Nucleus, Effect on Parkinsonian Motor Symptoms and Experimental Effects with CDNF

Antti Huotarinen

Parkinson’s disease (PD) is the second most common neurodegenerative disorder, affecting about 1% of people over 65. The cardinal motor symptoms of PD are mostly due to reduced dopaminergic signaling in the nigrostriatal system and can be effectively treated with dopaminergic medication. However, the most effective treatment, levodopa (L-DOPA), leads to dyskinesias or motor fluctuations....

Metal(IV) Phosphate Based Functional Materials for Selectively Harvesting Rare-Earth Elements from Bauxite Residue

Wenzhong Zhang

Inorganic metal(IV) phosphates with adjustable structural features, strong acid resistance and selective ion-exchange capabilities are an ideal class of materials to be applied in solid-liquid metal separation processes. The surface hydroxyl groups with ion-exchange capability also grant the metal(IV) phosphates with vast possibilities for further functionalisation and hybridisation.

Effects of dietary management on the energy metabolism of periparturient dairy cows: regulation of lipidome and transcriptome

Nanbing Qin

High-producing dairy cows suffer from metabolic stress, particularly during the periparturient period. The high nutrient demand of milk production leaves the animals susceptible to various metabolic diseases after calving. Improving the health and welfare of high-producing dairy cows has been a long-term goal of dairy research and it is critical for the sustainability of the dairy indust...

Diet, diabetes, and prevention of cognitive decline - Focus on lifestyle intervention

Jenni Lehtisalo

Late-life cognitive impairment and dementia are more common among individuals with type 2 diabetes, and these disorders also share risk factors, such as obesity, as well as protective factors, such as healthy diet. Diabetes prevention could improve cognitive performance later in life, and improvement in diet may potentially prevent cognitive impairment through several pathways. This stud...

Evaluation of epaxial muscle structure in dogs with spinal disease

Anna Boström

Epaxial muscle atrophy, decreased cross-sectional area (CSA) and increased fat infiltration has been found in dogs with spinal pathology. However, methods to quantify muscle structure have not been validated, and breed differences in the epaxial muscle architecture of dogs have not been considered in relation to spinal pathology. We aimed to validate a method to quantify epaxial muscle s...

Modelling circulation dynamics in the northern Baltic Sea

Antti Westerlund

Circulation and surface layer dynamics are of significant importance, for example, when considering how hazardous substances or nutrients are transported in the sea. The earliest studies mapping circulation patterns in the northern Baltic Sea were done before the Second World War and were based on lightship observations. Although the number of available observation points was low, these ...

Neurotoxin regulation and the temperature stress response in Clostridium botulinum

Gerald Mascher

Clostridium botulinum is a dangerous foodborne pathogen that forms highly resistant endospores and the extremely potent botulinum neurotoxin. Whereas endospores enable the survival and transmission of the organism in many harsh environments, the botulinum neurotoxin blocks neurotransmission and causes the severe and potentially lethal disease botulism in humans and animals. Both traits p...

Bioinformatics analysis of intron retention events associated with the minor spliceosome

Ali Oghabian

In the Eukaryotes, DNA sequences in genes are often interrupted by non-coding sequences called introns. These sequences are removed from the transcripts via a process known as splicing either while the genes are being transcribed (co-transcriptionally) or after transcription (posttranscriptionally). In higher eukaryotes two separate pre-mRNA splicing machineries have been described: the ...

Small airway dysfunction has been associated with different clinical features of asthma, such as symptom severity, exacerbations, and airway hyperresponsiveness (AHR). However, the diagnosis and monitoring of asthma focus on indices that reflect mainly large airway function, and no gold standard measure for small airways exists. Especially in children, the clinical significance of small ...
